Review Denoising and Compression Methods

In this paper, Image recognition is the process of identifying and detecting an object or a feature in a digital image or video. Feature extraction a type of dimensionality reduction that efficiently represents interesting parts of an image as a compact feature vector. A computer revolution has occurred not only in engineering field but also in Medical field, where vast amount of information must be processed very quickly and accurately. High resolution scanning techniques such as digital radiography, tomography, nuclear magnetic resonance, produces an image containing relevant information for medical analysis. The use of computers for handling image data in the healthcare is growing. The amount data produced by modern image generating techniques, such as Computed Tomography CT and Magnetic Resonance MR , is vast. This huge data might be a problem from a storage point of view or when the data is sent over a network. To overcome such problems data compression techniques are needed. Miss. D. D.

The Overview of Bayes Classification Methods

The Bayes methods are popular in classification because they are optimal. To apply Bayes methods, it is required that prior probabilities and distribution of patterns for class should be known. The pattern is assigned to highest posterior probability class. The three main methods under Bayes classifier are Byes theorem, the Naive Bayes classifier and Bayesian belief networks. Harshad M.
